Efficient isogeometric thin shell formulations for soft biological materials
, 2017 This paper presents three different constitutive approaches to model thin rotation-free shells based on the Kirchhoff-Love hypothesis. One approach is based on numerical integration through the shell thickness while the other two approaches do not need ...

Ain Shams Engineering Journal, 2018 This article aims to study the natural frequency of defective micro-/nano-plates because not only the existence of cut-outs in plates may be essential on the basis of their desired functionality but also the resonant frequency can be changed by cut-outs.

Acoustic radiation from lifting airfoils in compressible subsonic flow [PDF]
The far field acoustic radiation from a lifting airfoil in a three-dimensional gust is studied. The acoustic pressure is calculated using the Kirchhoff method, instead of using the classical acoustic analogy approach due to Lighthill. The pressure on the

The dynamics of cracks in torn thin sheets
, 2010 Motivated by recent experiments, we present a study of the dynamics of cracks in thin sheets. While the equations of elasticity for thin plates are well known, there remains the question of path selection for a propagating crack.

Mixed finite elements for Kirchhoff–Love plate bending
Mathematics of ComputationWe present a mixed finite element method with triangular and parallelogram meshes for the Kirchhoff–Love plate bending model. Critical ingredient is the construction of low-dimensional local spaces and appropriate degrees of freedom that provide conformity in terms of a sufficiently large tensor space and that allow for any kind of physically relevant ...

Alternative displacement frame formulations in hybrid-Trefftz Kirchhoff plate p-elements
Computer Assisted Methods in Engineering and Science, 2023 The thin plate p-elements considered in this paper are based on assumed displacement field chosen so as to a priori satisfy the governing Lagrange equation within the element.
